[0022] First opening 511, pressure bar 521

[0023] Second opening 512 Rod 5211

[0026] Cam 5221, Return spring 523 Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figure 1 and Figure 2 The present invention provides a liquid-fillable atomizing device 100, which includes a housing 1, an atomizer disposed inside the housing 1, and a liquid-filling structure 5.

[0029] Please refer to the following: Figure 2 The atomizer includes a reservoir 31 for holding atomizing liquid. The liquid filling structure 5 includes a filling channel 51 and a sealing assembly 52. ​​Specifically, the filling channel 51 includes a first opening 511, a second opening 512, and a third opening 513. The sealing assembly 52 includes a pressure rod 521, a pull rod 522, and a return spring 523. In this embodiment, the reservoir 31 and the liquid filling structure 5 are integrated as a single piece. The liquid filling structure 5 is located on the side of the reservoir 31. The reservoir 31 includes a vent pipe 311 and an atomizing core disposed within the vent pipe 311. The vent pipe 311 has an oil inlet connected to the reservoir 31, allowing the oil in the reservoir 31 to be supplied to the atomizing core.

[0030] In this embodiment, the first opening 511 communicates with the liquid storage tank 31. The second opening 512 is used to connect the liquid filling bottle 200. The pressure rod 521 is housed within the liquid filling channel 51, and one end of the pressure rod 521 extends from the third opening 513. The pressure rod 521 can move to a first position and a second position; when in the first position, the pressure rod 521 blocks the second opening 512 to prevent liquid leakage from the liquid storage tank 31. When in the second position, the pressure rod 521 opens the second opening 512; thus, the liquid filling bottle 200 and the liquid storage tank 31 are connected through the liquid filling channel 51. It should be noted that the first position of the pressure rod 521 in this embodiment is the position in which the pressure rod 521 blocks the second opening 512; the second position of the pressure rod 521 generally refers to a position different from the first position, and is also the position in which the pressure rod 521 opens the second opening 512. Preferably, this invention can be used for liquid addition when the bottle is inverted. When inverted, the liquid oil in the liquid addition bottle 200 flows into the liquid addition channel 51 through the second opening 512 and is injected into the liquid storage tank 31 through the first opening 511, thus realizing liquid addition.

[0031] In this embodiment, please refer to Figure 2 The return spring 523 is used to return the pressure rod 521 to the first position. A pull rod 522 is provided at one end of the pressure rod 521; the pull rod 522 is used to move the pressure rod 521 to the second position. Please refer to... Figure 3 When it is necessary to open the second opening 512, the pull rod 522 is pulled to operate and the return spring 523 is squeezed; when it is necessary to block the second opening 512, the squeezed return spring 523 is naturally extended and reset.

[0032] Preferably, please refer to Figure 3 The pressure rod 521 includes a rod body 5211 and a pressure plate 5212. Specifically, one end of the rod body 5211 extends from the third opening 513 to the outside of the housing of the liquid filling structure 5. In this embodiment, the liquid filling structure 5 is located inside the outer shell 1; the outside of the housing of the liquid filling structure 5 is the outer surface of the housing 1 that covers the liquid filling structure 5. Specifically, the pull rod 522 is rotatably connected to one end of the rod body 5211; the other end of the rod body 5211 is fixedly connected to the pressure plate 5212. In this embodiment, the rod body 5211 and the pressure plate 5212 are a single piece. The cross-sectional area of ​​the pressure plate 5212 is larger than that of the rod body 5211, increasing the sealing effect of the pressure plate 5212 in blocking the second opening 512.

[0033] Please refer to Figure 2 and Figure 3Preferably, the pressure rod 521 is sealed to the third opening 513. Specifically, one end of the rod body 5211 is sealed to the third opening 513. In this embodiment, the third opening 513 has a cylindrical annular wall, and a first sealing ring is provided between the cylindrical annular wall and the rod body 5211 of the pressure rod 521 to seal the connection between the rod body 5211 and the third opening 513. In this way, the inverted liquid filling bottle 200 allows the liquid oil to flow into the liquid filling channel 51 from the second opening 512, ensuring that the oil will not leak from the third opening 513 during the liquid filling process.

[0034] In this embodiment, the return spring 523 is a helical spring. The return spring 523 is sleeved onto the rod 5211, and its two ends abut against the pressure plate 5212 and the housing of the liquid filling structure 5, respectively. Thus, when the return spring 523 returns to its original position with its two ends abutting against the pressure plate 5212 and the housing of the liquid filling structure 5, the pressure rod 521 returns to its first position, and the pressure plate 5212 seals the second opening 512. Preferably, the second opening 512 has a recessed connecting portion for connecting the nozzle of the liquid filling bottle 200. A second sealing ring is installed on this connecting portion to seal the connection between the connecting portion and the nozzle of the liquid filling bottle 200, thereby ensuring no leakage during the liquid filling process.

[0035] Please refer to Figure 3 Furthermore, the pull rod 522 is provided with a cam 5221. During the rotation of the pull rod 522 relative to the rod body 5211, different parts of the cam 5221 are supported by the housing of the liquid filling structure 5, causing the pressure rod 521 to move in the first position and the second position.

[0036] Preferably, the housing of the liquid filling structure 5 is provided with a groove for cooperating with the rotation of the cam 5221. This groove has a limiting arc surface, which cooperates with the cam 5221 to stabilize the cam 5221 at a preset angle; thereby limiting the rotation of the pull rod 522 relative to the rod body 5211 to the current angle. This limiting arc surface increases the contact area between the housing of the liquid filling structure 5 and the cam 5221, thereby increasing friction and enabling the cam 5221 to be stabilized in any position.

[0037] In this embodiment, when the pull rod 522 is rotated to 90 degrees relative to the rod body 5211, the pressure plate 5212 of the pressure rod 521 is furthest away from the second opening 512.

[0038] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these all fall within the protection scope of the present invention.
